We definitely know, at least, that several members of the English Royal Naval Reserve had assumed names when they enlisted on the CSS ALABAMA. Certainly, other crew members would also have had assumed names, for one reason or another. Besides this, we also know that there were many crew members who left the vessel at Singapore, and other ports of call, throughout the entire cruise of the ALABAMA, either through desertion or other means of discharge.
If you claim to have the rolls of the CSS ALABAMA throughout her entire cruise, and to know the alias used by every crew member, who took up an assumed name, then you would have to be the most knowledgeable person in the world about the vessel, now, or in the past, even more so than anyone who had served on the vessel, including the officers who wrote about the cruise. Yet every student (I don't claim to be a full time student of the CSS ALABAMA in particular, just a student of the CS Navy personnel, in general) knows that there are so many mysteries of the vessel, including many that will never ever be solved at this late stage in time.
To ignore completely, the statement that Samuel Risien had ever served on the CSS ALABAMA, is to reject the facts, as shown in Confederate Veteran magazine, and that his acceptance as a member of the CSN by the Texas UCV, was a major error on their part. The steamer ALABAMA (more commonly known as the JAMES BATTLE), at Mobile, was never ever commissioned into the Confederate Navy, and thus cannot be classified as a "CSS" ALABAMA. It was stated to have been used by the Confederate Army.
As for the alias Henry Eustachia/Ustakan/Uslakan, used by a gentleman whose true surname was Kernot, he actually signed an affidavit at London, on August 11, 1864, in front of a "London Commissioner to Administer Oaths in Chancery," as did several other crew members of the CSS ALABAMA, including James Higgs and George Yeoman, amongst others. This proves that some others had assumed names, on the vessel, and we don't know all of those who did so.
As for the discussion about my citing Marvel, you know full well that I had used the material from his roster, and I had correctly, and properly cited that source. My private messages to you have reflected the entire nature of this matter, which you still seem to be ignoring.
